  • Look Inside

 This is a report of a case of spinal tumor associated with hydrocephalus. An 81-year-old male came to our hospital complaining of neck pain. An MRI scan revealed a mass in the region of the second and third cervical vertebrae. Three weeks after the initial visit, a gait disturbance, urinary incontinence, and dementia developed and rapidly progressed. A computed tomography (CT) scan showed enlargement of the cerebral ventricles. After diagnosing hydrocephalus secondary to the spinal tumor, the tumor was excised. The patient's CSF protein level was elevated to 286mg/dl at the time of the operation, and the pathological diagnosis of the tumor was neurilemmoma. The patient rapidly recovered from all symptoms postoperatively, and a CT scan 3 weeks after the operation revealed a reduction in ventricular size. Spinal tumors accompanied by hydrocephalus are well known by neurosurgeons, but since they are poorly recognized by orthopaedic surgeons in Japan, diagnosing hydrocephalus may be difficult when a patient with a spinal tumor suddenly develops incontinence and dementia. The majority of spinal tumors complicated by hydrocephalus have been located below the thoracolumbar junction. Cases of cervical nuerilemmoma associated with hydrocephalus are rare, and only 5 cases, including our own, have been reported. We conclude that hydrocephalus should be ruled out whenever a patient with a spinal tumor suddenly develops a gait disturbance, incontinence, and dementia.
